New ‘Heat Saviour’ could save up to £2,000 on heat pump costs

• The Hewer Heat Saviour goes underneath a standard hot water cylinder
• It aims to reduce waste, cost and downtime for installers 
• Heat Saviour aims to save up to £2,000 on installation costs

Hewer, a heating firm that makes and installs heating technology, has launched ‘Heat Saviour’, a low-carbon technology that could save up to £2,000 when they install heat pumps by cutting down on labour costs. 

The product has been designed to be placed underneath a standard hot water cylinder and Stuart Hesk, director, Hewer, said it is to work with all major heat pump brands and is no longer exclusive to one manufacturer. 

Heat Saviour also aims to minimise system downtime, as well as have built-in backup heating during maintenance or a pump failure. 

Hesk said the reason behind the Heat Saviour launch was because installing and retrofitting heat pumps can be “complex, costly and disruptive”. 

He continued: “They are often designed with non-universal parts, requiring entire heating systems to be ripped out, systems that could have years of use left in them. 

“Heat Saviour is a much smarter and cheaper way for engineers to install and maintain a heat pump, making property management easier and improving residential satisfaction.”

A further reason behind the creation was to reduce the amount of waste, cost and downtime that installing and retrofitting heat pumps can cause, saving homeowners around £2,000 in installation costs. 

The product has cut glycol use by 80%, making them better for the environment, and allows radiator maintenance without the costly expense of having to drain and replace the glycol solution. 

Hesk said the unit is ideal for social housing and council projects, as it means homes won’t have to overhaul their entire pipework to make a home “heat pump ready”. 

The other benefits include: 

• Reduces installation time and labour costs – ideal for retrofit programs
• Minimises system downtime – essential for keeping tenants warm 
• Built in backup heating – ensures no loss of heating during maintenance or pump failure
• Works with all major heat pump brands 
• Supports compliance with low-carbon heating initiatives and net zero targets

For installers, Hesk said the benefits are that they use standard off the shelf components, they are pre-engineered and ready to install. It also supports retrofit work in older or mixed heating systems. 

The launch coincides with the recent government pledge to double the Boiler Upgrade Scheme to £295m and launched a public awareness campaign to spotlight the grant. It also cut the 1m rule to speed up adoption.
